Barack Obama is being endorsed by fellow Sen. John Kerry, the Democrats’ 
2004 presidential nominee who lost to George W. Bush that year and gave up his own plans for a 2008 run a year ago. Kerry, a senator from Massachusetts, planned to announce his support Thursday at 11 a.m. EST at a rally at the College of Charleston, said a Democrat familiar with Kerry’s decision. The 2004 nominee was to argue that Obama can best unite the country and has the potential to create transformational change, the person said.
